成果简介	NOVELTY - Invention relates to laser communication systems in open space and is intended for establishing communication lines between aircraft. Said technical result is achieved by the fact that simultaneous transmission and reception of data streams is carried out at least at two wavelengths of laser radiation λ1 and λ2, at that, 20 nm<λ1–λ2<40 nm, separating the data streams both by radiation wavelength and polarization direction with their simultaneous transmission and reception, providing collinearity of directions of polarization of transmitted streams and their orthogonality to directions of polarization of received streams. Complex includes a second receiving-transmitting (RT) unit with a laser transmitter wavelength of λ2 and a radiation polarization direction, coinciding with the polarization direction of the first laser transmitter, spectral-dividing mirrors 5, 6 are additionally introduced into the RT units, completely reflecting the radiation of the laser transmitter and transmitting the received radiation, prismatic monoblock 8.2 is introduced into polarization-spectral splitter 8, coarse aiming unit 1 is made in the form of mirror telescope 1.1 with optical hinge 1.2. USE - Communication equipment. ADVANTAGE - Increased volume of transmitted and received information, increased reliability of operation by minimizing the probability of erroneous bits (not more than 10−9) of transmitted information and the possibility of simultaneous reception and transmission over long distances by laser communication users of information streams at different wavelengths with a common optical antenna. 4 cl, 3 dwg
